In May 2003, O’Brien, et al. could not see the logic in many CPM schedules. In the intervening years, a number of scheduling experts, including this author, have posited that the critical path method (CPM) is past its prime. However, seemingly, nothing much has changed as mainstream scheduling practice continues to be hindered by overly detailed, flawed schedules that stakeholders cannot decipher―much less collaborate on―in the face of the Internet social revolution that cries out for more engaging, transparent, and “stakeholder-centric” processes. In this keynote, Dr. Gui presents to professionals in Peru the graphical path method introduced in 2008 in response to O’Brien’s plea for a return to scheduling fundamentals.
